Abstract: As an important part of marine pastures, the artificial reefs play an important role in increasing and optimizing fishery resources, improving the marine ecological environment and adjusting the industrial structure of marine fisheries. The planning, designing, constructing, accepting and subsequent monitoring of artificial reefs are the keys to the technical aspects of building marine pastures. In order to give a full play to the functions of artificial reefs, it is necessary to carry out fine and large-scale investigations on artificial reefs. The traditional methods for underwater surveys are highly restricted and often lead to low operation efficiency. The side-scan sonar can be used to obtain high-resolution images of seafloor targets and the multi-beam bathymetry system can be used to obtain high-precision topographic data of the seafloor. Thus, the combination of the two techniques can provide accurate information about the topography and geomorphology of the seafloor and the spatial information on the artificial reefs for the construction of the artificial reefs, and then provide effective technological support for the design, deployment and monitoring of the artificial reefs. Based on the current research and technical literatures on the artificial reef construction at home and abroad and from the aspects of the early site selection, construction and deployment, empty square estimation and late monitoring of artificial reefs as well, the applications of hydro-acoustic technology and related acoustic equipment (e.g. side-scan sonar and multi-beam bathymetry system) in the artificial reef construction are summarized, and the future application prospects of this technology are expected.
